I actually bought this to form the base of a custom three-tier keyboard stand, coupled with the 18952 Stacker expansion and shelves I constructed myself.
It's easy to assemble, which will probably come as a relief to most and it's obvious how it goes together. The black finish feels like quality - I've bought many a stand in the past where the finish starts to flake away but no such qualms with the K&M.
It's easy to adjust - you can set the height of the stand via the four feet and a nut locks it into place. Two sturdy diagonal braces lock the legs into the open position, so you don't have to worry about knocking into it from the side and the legs folding back in.
The width is similarly easily adjusted and you could easily accommodate a full 88-note keyboard on here, no matter how heavy, due to the strong construction. There are some adhesive rubber pads which you can stick on to protect the underside of your keyboards.
Pros:
- very easy to assemble in minutes
- good quality parts, well finished and solidly-made
- no danger of the legs collapsing thanks to the locking supports.
- good range of adjustment
- expandable with other tiers.
Cons:
- a little heavy, but reassuringly so!
